Mikitenko, E. K. published the artcileCyclazines and their analogs. 1. Thiazolopyrimidopyrimidines, Recommanded Product: 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1992), 692-7, database is CAplus.
3-Aminothiazolo[3,2-a] pyrimidinium salts (I; R = H, OMe) were prepared in 47-71% yield by treating 6-substituted 2-mercaptopyrimidines with Ph α-cyanobenzylbenzosulfonate, α-bromopropionitrile, or Et bromocyanoacetate and heating. Vilsmeier reaction (DMF, POCl3) of the pyrimidinium salts led to Me formylation in the 5 position and to formation of a new heterocyclic system (thiazolopyrimidopyrimidine). The formyl-substituted thiazolopyrimidopyrimidines were separated as crystalline dark-blue substances having in addition to intense UV absorption bands a less intense, broad absorption band at ∼600 nm with well expressed vibrational structure. The thiazolopyrimidopyrimidines were treated with N-containing heterocyclic quaternary salts or nucleophilic agents (malonodinitrile) to give polymethine dyes.
